Toronto-based Dushnisky had announced he would step down last month after two years in the role with the South Africa-headquartered gold miner, with CFO Christine Ramon appointed interim CEO.
Dushnisky had reiterated on a conference call earlier this month his decision to resign was a personal one to be closer to family.
Bloomberg had reported Dushnisky was pushed to leave after shareholders asked for further investigations into a bonus payment by his former employer Barrick Gold which he hadn't initially disclosed, although the company told the wire service it did not threaten an investigation into a bonus nor request the resignation.
